T o all lwir-0m t may concern.'

Be it known that I, ERNEST ENOS, -a British subject of the Dominion of Canada, residing at Tampa, in the county of Hillsborough and State of Florida, have invented certain new and useful Improvements in Resilient Metal Tires; and I do hereby de- Clare the. following to be a full, clear, and

exact description of the invention, such as will enable others skilled in the artto which it appertains to make anduse the same. Y

VThe present invention relates to improvements in meta-l resilient tires, and has for anV object-to provide a tire of this character vto take the place of the usual-pneumatic tire as atpresent extensively employed on automobiles and the like.

Another obj ect of the invention is to kprovide a tire of this character which will possess all the resiliency of the pneumatic tire and at the same time avoid the trouble and inconvenience incident to the use of the eoy pneumatic tire, which involves replacement of tires in case of puncturing.

It is a further object of the present invention to provide an improved resilient metal tire of an economical and simple construction applicable to wheels of standard type with little modification.

In the accompanying drawings forming a part of this application, and in which similar reference symbols indicate corresponding parts in the several views:

Figure 1 is a side elevational view of a wheel constructed according` to the present invention and shown partially in section.

Fig. 2 is a horizontal` sectional view taken on the line 2 2 in Fig. 1.

Fig. 3 is a plan view of one of the spring segments laid out.

Fig. 4 is a cross sectional view of one of the segments in the curved position assumed when in actual use. y

Fig. 5 is a cross section through the central portion of one of the sections.

Fig. 6 shows one of the lugs for securing the demountable rim to the wheel.

Fig. 7 is a cross sectional view of a slightly modified form of the invention; and

Fig. 8 is a fragmentary elevational view, partly in section, of the same.

Referring more particularly to the drawings, 1 designates the hub, 2 the spokes, and

3 the felly of a wheel body, which may be Y Specification-Of Letters Patent. Patented Jlllh "Y,v 19211 Application filed January 5, 1920. Serial No.- 349,517# u i felly is beveled or inclined transver,selyfand ,1

at the higher side thereof iS Povided'with an integral ring 5, c

Lugs 6, shown in detailin arev spaced about the lower edge of the felly and are beveled as indicated at 7 on their faces next the tire for coperating with Aa 'similarly-,formed inner face ofc-the ring 5, The

lugs 6 have perforatedears 8 .extending iiiv wardly from the same` to receive .bolts9jk which pass into the body of the yfelly 3.

The lugs 6 also have associated, and pref` erably formed integral therewith' elongated tongues 10 which pass transversely across to present a straight transverse surface on their outer edges to thedemountable rim 11. This rim 11 is made of a -diaineterto freely slip over the face 4 of the felly, and

the same is'wedged outwardly on the' inclined faces of the ring 5 and lugs 6, when the lugs are put in place and secured by the fastenings 9. The condition of assembly is indicatedin Fig. 2.

The rim 1l is formed at its edges with annular channels 12 adapted to receive beads 13 formed on the inner ends of metallic curved segments 14. The segments are made of a suitable width and are formed substantially in the manner shown more particularly in Figs. 3, 4 and 5, the segments being cut or stamped from resilient metal to a shape resembling a barrel stave with the ends thereof provided with the beads13 and the central wider or bulged portion stamped out or otherwise provided with integral flanges 15 at right angles to the segments 14 andv inwardly thereof. l

As shown in Fig. 5, thesegments l14 are Y curved in a' direction circumferentially of the tread portion of the segments, prevent-l ing any cracking or rupturing thereof and at the saine time not interfering with the proper resiliency thereof.

The channels 12 of the demountable rim 11 are made up of claws 16 and 17 bent ciriro cularly and have a gap separating their free i ends to admit the inner portions of the segments 141; adjacent the beads 13.` These claws 16 or 17, or one of them, may be bent about the beads 13,"01 the demountable rirn 11 maybe of the split type and thebeads 13 maybe slipped circumferentially into the l [channels 12 at the split portion of the 'rim and slid aroundto their proper places, after )Whichlthe rim may be closed and mounted on the y Wheel. s
